How it's used
Literary and formal, this term is rarely used in casual daily speech where 日頭 is the standard choice. It is primarily encountered in written texts, weather reports, or scientific contexts discussing light and time. Using it in a normal conversation about your daily schedule will sound overly poetic or stiff.
Examples
The daylight hours are really long in summer.
Do you prefer the daytime or the nighttime?

Common mistake
Learners often mistake this for a common noun for 'day' like 日, but it specifically refers to the period of light. Do not use it to count days, as in 'three days', where you must use 三日 instead.
